Looking for correct crown Ref 2964 1

Good morning all! Recently got a great deal on this 58’ Seamaster ref 2964 1 sc cal 520. Keeping good time and a fantastic heavy patina dial. I think crystal and crown to be unoriginal (though I believe crown is genuine). Bought as a wearer not to worry about too much. However, I would like to put the correct crown on it. Through all my searches, I can only find two references that match this. Both of those have different crowns as well. Any help in the right direction would be greatly appreciated!

Appreciate the response
